A Study on the Operation Behaviors of Saturated Synchronous Generators Considering the Effect of Multiple Factors

摘要

In the paper the measurements to increase the calculation accuracy of synchronous generator parameters by using finite element (FE) method are studied in detail at first. Then through a lot of calculations, a series of curve families of a 300MW turbo generator are gotten, including saturation power-angle curve, magnetizing characteristics corresponding to different power angles and the curves of saturation parameters versus some operation conditions. These curve families reflect the effects of multiple factors and cross-magnetization on saturation.
